#519 Issue closed: pre-copy usb host drivers¶
Labels: enhancement, fixed / solved / done

hi:
I found rear will pre copy many kernel drivers, like network and storage
drivers. it will help rear recovery on different hardware. maybe we
should copy the usb host driver (kernel/drivers/usb/host) too.
when I make backup on a machine with only usb2 and restore to another machine with usb3, I found I can not use the keyboard, because the keyboard need xhci_hcd usb3 host driver. and to my surprise I found on many usb3 machines even the usb2 port is driven by xhci_hcd, not by ehci_hcd. so although the keyboard is plug into usb2 port, it is still useless. and nowadays we don't have ps/2 port on these new machines. so now I include "xhci_hcd" to my local.conf, but I think maybe rear should make it as default pre-copy modules.
I don't know if "23_storage_and_network_modules.sh" is a good place to put usb host driver. or there is some better place to pre copy the usb host dirver, especially the "xhci_hcd" driver.

Please confirm if it works.

hi schlomo:
I think it is fine. I test on one machine and the usb3 module is copied
correctly.
thanks a lot for your help!!

@schlomo In case the source is running on an xhci driver only (no ehci
module loaded). Then, at least on Arch Linux with Rear 2.00 git, only
xhci-pci(.ko.gz) is copied to the ReaR recovery medium. Next to
copying (uhci|ehci|xhci|ohci)-hcd modules, could it be wise to also
force copy their counterpart (uhci|ehci|xhci|ohci)-pci modules too?
